Loaded from forklift initially, pipe secured by worker (8)
I believe the answer is:
affluent
'loaded' is the definition.
(loaded can mean very rich)
'forklift initially pipe secured by worker' is the wordplay.
'initially' indicates taking the first letters.
'pipe' becomes 'flue' (flue pipe is a kind of pipe).
'secured by' is an insertion indicator (inserted letters are held or secured).
'worker' becomes 'ant' (worker is a type of ant).
The first letter of 'forklift' is 'f'.
'f'+'flue'='fflue'
'fflue' going into 'ant' is 'AFFLUENT'.
'from' acts as a link.
(Other definitions for affluent that I've seen before include "Very well off, quite rich" , "Well-to-do, wealthy" , "Flute fan may be wealthy" , "Well off, having plenty of money" , "comfortable" .)
